DO grab a big group of friends for a Friday night dinner at El Coyote and share plates of guac-topped nachos with the table amongst festive garland and mini Christmas trees. DRINK with a discount during happy hour with the award-winning $8 house margaritas from Casa Vega and sip all Saturday night under the tinsel-clad ceiling. EAT inside a Tudor-style pub on Sunday for an evening of prime rib and holiday decor at Tam O'Shanter.
